Background
The net/mlx5 package is a component of the Linux Kernel ecosystem. It provides support for Mellanox ConnectX network adapters, enabling high-performance networking capabilities. The package includes various drivers and firmware for Mellanox network devices. This vulnerability specifically affects the fw reset flow of the halting poll mechanism.
Vulnerability Detail
The vulnerability arises from the absence of proper synchronization in the fw reset flow of the halting poll mechanism in net/mlx5. This can lead to race conditions and potential security vulnerabilities. An attacker may be able to exploit this vulnerability to execute arbitrary code, escalate privileges, or cause a denial-of-service condition. The vulnerability was introduced in version v5.10 of the Linux Kernel and has been fixed in version v5.10.97.
